My Brain is Inconsequential and Unnecessary (Apparently)

Katherine sat directly above and behind me while I was playing video games today.  I could feel her eyes boring into he back of my skull; it was a little very creepy.  When I mentioned this to Mom, she informed me that Katherine was trying to think of a way to get the lid of my head off and empty it out so that she could use my empty gutted skull as a cup.  When I protested, Mom said, "What?  She has no opposable thumbs!  It must be contemplated on!"
